Specific embodiment

Hereinafter, about the touch panel pen screening technique, touch panel system, touch surface that can write component of the invention Plate pen is carried out by taking embodiment A, embodiment B and embodiment C as an example with that can write component, touch panel and display device Explanation.

[the touch panel pen screening technique that can write component]

The touch panel pen of embodiment A filters out the touching for meeting following condition A1-1 with the screening technique that can write component Control panel pen, which is used, can write component as touch panel pen with can write component.

It should be noted that 60 degree refer to, the direction parallel with the surface that can write component with touch panel pen is set as 0 Degree tilts 60 degree relative to surface.

Fig. 1 and Fig. 2 is the section for showing the touch panel pen embodiment that can write component 10 of embodiment A Figure.The touch panel pen use of Fig. 1 and Fig. 2, which can write component 10, has resin layer 2 in a face of substrate 1.

The average value of kinetic force of friction is 1.0gf or more 32.0gf or less.

Average value (the F of kinetic force of friction_k) it is more preferably 2.0gf or more 25.0gf or less, further preferably 2.5gf or more 15.0gf or less.

The screening technique for writing component of embodiment A preferably filter out meet following condition A1-4 write structure Part.By meeting condition A1-4, can be easy so that writing sense when continuous writing is good, while being readily able to inhibit pen tip Abrasion.

The standard deviation of kinetic force of friction is 0.5gf or more 18.0gf or less.

[the touch panel pen screening technique that can write component]

The touch panel pen of embodiment B is filtered out with the screening technique that can write component meets following condition B1-1 and item The touch panel pen of part B1-2, which is used, can write component as touch panel pen with can write component.

Fig. 1 and Fig. 2 is the section for showing the touch panel pen embodiment that can write component 10 of embodiment B Figure.The touch panel pen use of Fig. 1 and Fig. 2, which can write component 10, has resin layer 2 in a face of substrate 1.

The touch panel pen of embodiment B can meet condition B1-1 and condition B1-2 with that can write component with a surface, Can also two surfaces meet condition B1-1.

Hereinafter, touch panel pen is known as " can write component " with that can write component sometimes, condition B1-1 and item will be met The surface of part B1-2 is known as " writing surface B ".

The touch panel pen of the embodiment B screening technique that can write component, which filters out to have, meets above-mentioned condition B1-1 Component can be write as touch panel pen with can write component by using with the touch panel pen on the surface of condition B1-2.Hereinafter, to item The technical idea of the design of part B1-1 and condition B1-2 is illustrated.

Firstly, being illustrated to the technical idea of the design of condition B1-1.

Condition B1-1 is the parameter about kinetic force of friction.In the case where kinetic force of friction is small, become the touching slided when writing Sense is unable to get high-caliber writing sense.That is, in order to obtain high-caliber writing sense, it is believed that the kinetic force of friction of prescribed level is very It is important.

The present inventor is further studied the relationship of writing sense and kinetic force of friction, as a result, it has been found that, even if having The kinetic force of friction of prescribed level, when there is no the variation of the kinetic force of friction of each time, people can also experience the feeling of sliding.And And the present inventor further study as a result, it has been found that, people can be felt with surprising short interval friction variation.

Fig. 8 and Fig. 9 is an example for showing the kinetic force of friction of each time with pencil when writing on paper, and Fig. 8 is every 20 milli The figure of second measurement kinetic force of friction, Fig. 9 are the figures of every 1 millisecond of measurement kinetic force of friction.The longitudinal axis of Fig. 8 and Fig. 9 indicates kinetic force of friction, horizontal Axis indicates time (millisecond).In addition, the determination condition of the kinetic force of friction of Fig. 8 and Fig. 9 is load 100gf, writing speed 14mm/s.

Difference due to measuring interval may validate that by the comparison of Fig. 8 and Fig. 9, the fluctuation range of kinetic force of friction is substantially not Together.Its reason is considered that the spacing of the fiber on paper surface produces influence.Specifically, be considered due to: at 1 millisecond (0.001 Second) under interval, the deviation of the pencil number of crossing paper fiber is big when measurement every time, and under 20 milliseconds of (0.02 second) intervals, often The deviation that pencil crosses the number of paper fiber when secondary measurement becomes smaller.In other words, it is believed that: since 1m seconds intervals are not equalizations Value, therefore deviation is big；And 20m seconds intervals are the values equalized, therefore deviation becomes smaller.

The present inventor's production is various to write component and is similarly measured, with sensory evaluation (the writing sense that people feels) It compares, as a result it has surprisingly been found that people can distinguish the deviation of the frictional force at the 1m seconds this extremely short intervals in interval as book Write sense.

Condition B1-1 requirement: the frictional force at 0.001 second interval is measured under the defined conditions, is calculated by measurement result Kinetic force of friction standard deviation (σ F_k) it is 2.0gf or more 15.0gf or less.

σF_kIn the case where less than 2.0gf, the variation of the kinetic force of friction of each time is small, because this person feels the sense of touch of sliding, nothing Method obtains high-caliber writing sense.

In addition, σ F_kIn the case where 15.0gf, the movement of touch panel pen feels heavier, or feels that pen tip is hung Firmly, it is unable to get high-caliber writing sense.In addition, σ F_kIn the case where more than 15.0gf, the pen tip with touch panel pen is worn Become violent tendency.

Then, the technical idea of the design of condition B1-2 is illustrated.

By meeting above-mentioned condition B1-1, it is readily able to writing sense of the acquisition pencil when writing on paper.But in order to " the high-caliber writing sense " for surmounting the sense of the writing with pencil when writing on paper is obtained, is insufficient merely with condition B1-1 's.

The present inventor is further studied to sense is write.As a result, it has been found that even if the case where meeting condition B1-1 Under, the also example of visible hand fatigue everywhere when writing for a long time.Also, the present inventor opponent hold it is fatigable write component and The tireless component of writing of hand is compared, as a result, it has been found that, the alteration mode of the kinetic force of friction of each time of the two is not It has differences.Specifically, discovery: holding the kinetic force of friction of the fatigable each time for writing component about hand, such as Fig. 9 institute Show, kinetic force of friction, which is reduced to close to before the value of 0gf, becomes the phenomenon that rising repetition；And structure is write about hand is tireless The kinetic force of friction of each time of part, kinetic force of friction, which is reduced to close to after the value of 0gf, becomes the phenomenon that rising repetition.

According to above technical idea, present inventor have discovered that being down to 3.0gf by kinetic force of friction moment hereinafter, when long Between write when hand will not tired jail, can obtain surmount with pencil on paper write when writing sense " high-caliber writing Sense ".

It is 3.0gf time scale below that condition B1-2, which requires the kinetic force of friction in whole minutes of kinetic force of friction, It (T) is 15% or more 90% or less.

If above-mentioned time scale feels that the time scale of friction becomes more in less than 15%, writing, hand when writing for a long time It is easy fatigue.In addition, being easy to feel the sense of touch of sliding in writing, being unable to get Gao Shui if above-mentioned time scale is more than 90% Flat writing sense.

In condition B1-2, kinetic force of friction is that 3.0gf time scale below is preferably 20% or more 85% or less, more preferably It is 30% or more 80% or less, further preferably 50% or more 75% or less.
